Interpreting a Division Computation

Alignments to Content Standards: 6.NS.B.2


Use the computation shown below to find the products.


  1. $189\times 16$
  2. $80\times 16$
  3. $9 \times 16$


  1. $189\times 16 = 3024$. The computation shows that $3024 \div 16$ is $189$ with a remainder of $0$. So it must be that $189\times 16 = 3024+0$.

  2. $80\times 16=1280$. We can see this in the second step of the division algorithm. Sol_1_9c923adc41db2e4a4bd50185b1c80116

  3. $9 \times 16=144$. We can see this in the last step of the division algorithm. Sol_2_f72644aa2f7db41212a806f26a3a683a

I love how this task asks for conceptual understanding of something usually taught as a rote procedure. To be successful with this task, students must make sense of the procedure and how place value is represented and abbreviated within it.

Thanks for your comment! Let us know how it goes if you get a chance to try it with students.
